Determination of Available Service Capacity in Dynamic Network Access Domains

2. The system of claim 1 , wherein the dynamic network is a Metro Ethernet Access network with at least one of a ring or hub-spoke topology.

3. The system of claim 1 , wherein an analysis component tests conditions put forth by a Service Level Agreement (SLA) based upon the current topology.

4. The system of claim 3 , wherein the conditions put forth by the SLA specify a predefined capacity to be delivered to a customer, the analysis component employs the predefined capacity to determine if the new service can be activated.

5. The system of claim 1 , wherein the auto topology discovery component determines an optimal service path for the new service.

6. The system of claim 1 , wherein the auto topology discovery component automatically evaluates a value for at least one of available node, link or EAD (Ethernet Access Domain) capacity, wherein the value is employed to determine if the new service can be established, the value corresponding to the ANc, ALc, ARc, or ADc.

7. The system of claim 1 , wherein an input device can be employed that receives input capacity values from a user.

9. The system of claim 8 , further comprising means for generating an optimal service path by determination of a service hub, wherein the optimal service path is employed to determine service activation.

10. The system of claim 9 , further comprising means for displaying the optimal service path.

11. The system of claim 8 , further comprising means for allocating bandwidth to a customer on activation of the new service.

12. The system of claim 8 , further comprising means for interacting with the system to establish a baseline, wherein the baseline is employed to initialize the system.

13. A method for capacity aware service activation, the method comprising: monitoring and tracking a change in available network capacity; checking if conditions put forth by the SLA are satisfied as a function of the available network capacity, the checking being based on an available node capacity (ANc), an available ring capacity (Arc), an available link capacity (ALc), and an EAD over-subscription factor (Eof); activating a new service if the SLA conditions are satisfied; determining new available capacity once the new service is activated; and extending network capacity when service activation is rejected.

14. The method of claim 13 , the act of extending the network comprises replacing one or more of low capacity nodes or links with those of higher capacity.

15. The method of claim 13 , further comprising checking SLA conditions using the following formula: UNIcir<((MIN(ANc, ARc, ALc))*(Eot); where UNIcir is a committed information rate for a UNI.

16. The method of claim 13 , further comprising providing the change in available capacity to a capacity planning tool that assists to prevent bottlenecks in the network.

17. The method of claim 13 , the act of determining new available capacity comprises calculating at least one of available node, link or ring network capacity.
